Ryde was created originally in 1894 with the abolition of multi-member districts, from part of Central Cumberland and named after and including Ryde. It was abolished in 1904 with the downsizing of the Legislative Assembly after Federation, but recreated in 1913. In 1920, the electoral districts of Ryde, Burwood, Drummoyne, Gordon and Willoughby were combined to create a new incarnation of Ryde, which elected five members by proportional representation. This was replaced by single member electorates, including Ryde, Burwood, Drummoyne, Eastwood, Gordon and Willoughby for the 1927 election. Ryde was abolished in 1968, being partly replaced by Fuller. In 1981, Fuller was abolished and replaced by a recreated Ryde and Gladesville. In 1991, Ryde was abolished again, but in 1999, Gladesville and Eastwood were abolished and largely replaced by a sixth incarnation of Ryde and Epping.
Ryde has historically tended to be a marginal seat, being won by both major parties on separate occasions. Presently, however, it is a very safe Liberal seat; Dominello holds it with a majority of 25 percent.
